A widget to select a color

[Joaquim Duran <joaquinduran adtelecom es>]

Dear all,

I should include in the current development application, a widget to let
the used select a color. I've found Gtk::ColorSelection. This widget has
color wheel with other widgets to select the color using other parameters.

I'm only interested to use the color wheel but not the whole widget. The
color wheel could be used as a stand-alone widget? Any alternative?

Thanks and Best Regards,
Joaquim Duran
